Hazardous waste landfill overall performance evaluation and life prediction method and system

Abstract

The invention discloses a hazardous waste landfill overall performance evaluation and life prediction method and system. The method comprises the steps of obtaining aging parameters of a current timenode of a hazardous waste landfill; calculating a life prediction variable value of the current time node based on the obtained aging parameter; comparing the obtained life prediction variable of thecurrent time node with a corresponding end-of-life threshold, and if the life prediction variable is greater than the end-of-life threshold, ending the life of the hazardous waste landfill; otherwise,recalculating the aging parameter of the next time node, and repeating the judgment process; and repeating the cycle until the service life of the hazardous waste landfill is ended. According to theinvention, the HELP model is selected as an overall performance evaluation model, an HDPE film and a guide and discharge medium performance parameter change model are introduced, and long-term performance prediction is achieved through coupling of the HDPE film and the guide and discharge medium performance parameter change model.

Description

technical field [0001] The invention relates to the technical field of life prediction of hazardous waste landfills, in particular to a method and system for overall performance evaluation and life prediction of hazardous waste landfills. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the rapid development of my country's industry, the annual output of solid waste has gradually increased, and the types and quantities of hazardous waste have also increased. Safe landfilling of hazardous waste is an effective measure to contain and segregate hazardous waste to reduce the transfer of harmful pollutants in the environment. [0004] Hazardous landfills are prone to wear and tear during long-term operation, and their operating life will be shortened. After the life ends, they will lose their role in disposing of hazardous waste. In addit...

AI Technical Summary

Problems solved by technology

Compared with life prediction in other fields, the long-term performance degradation of hazardous waste landfill projects leads to landfill functional failure and decommissioning problems, which lag behind

[0005] At present, for the long-term performance degradation and overall life of HWL, a framework system for overall life prediction has not yet been established. How to characterize the engineering life of hazardous waste landfills, life indicators, how to select indicator thresholds, and how to evaluate their life There are no answers to such questions, which seriously affects the extensive development of HWL life prediction research and related applications.
